Delegate Curt Anderson, D-District 43, introduced a measure in the House of Delegates on Thursday that would make marijuana legal for adults 21 and over and create a system to regulate and tax it like alcohol.

The measure would also direct the state comptroller to license marijuana retail stores, wholesale facilities and testing facilities.

The bill would create an excise tax of $50 per ounce on wholesale sales and direct proceeds to fund treatment programs to prevent alcohol, tobacco and drug abuse.

Last November, voters in Colorado and Washington state approved measures to make marijuana legal for adults 21 and older.
